Speaker: Maciej Malicki
Title: Groups of isometries of Polish ultrametric spaces
Abstract. We will characterize Polish ultrametric spaces whose isometry groups have a neighborhood basis at the identity consisting of open subgroups with ample generics. We will also define Polish ultrametric W-spaces and give a characterization of W-spaces whose isometry groups have uncountable strong cofinality.
